"We are established here and we don't know if we are going to survive, I would consider very strongly searching elsewhere to start up again because I don't see a future in Ontario the way it stands," Gerry Mastronardi told CBC.

Another grower, Jamie Diniro, told CBC his gas bill in December 2016 was around $19,000.

But after the cap-and-trade program came into effect, his bill for January 2017 skyrocketed to more than $41,000.

Diniro said Ontario is getting taxed more heavily than other provinces.

"Alberta is settled and British Columbia is settled and we are getting hammered ... we are all Canada here, but we (in Ontario) seem to be getting the brunt of the high tax," Diniro said.

Diniro told CTV News if things don’t change, he may move his operation to the United States, where natural gas prices are cheaper.

“I’ve lived here for 46 years, but on the other hand, I need to feed my family,” Diniro told CTV.
